Kodi mfundo ya ntchito ya chisindikizo cha mafuta a valavu ya galimoto ndi iti?
Chotsekera mafuta cha valavu ya injini ndi chinthu chofunikira kwambiri chotsekera mu injini. Ntchito yake yayikulu ndikuletsa mafuta a injini kulowa mu intake manifold, exhaust payipi, ndi chipinda choyaka moto, komanso kupewa kutuluka kwa mpweya wosakanikirana ndi mpweya wotulutsa, potero kuonetsetsa kuti kutsekerako kukugwira ntchito bwino komanso kugwira ntchito bwino mkati mwa injini.
Mfundo yogwirira ntchito imadalira kwambiri kapangidwe kake kapadera komanso zinthu zake. Tsatanetsatane wake ndi uwu:
Njira Yotsekera: Chisindikizo cha mafuta cha valavu chimayikidwa mozungulira tsinde la valavu ndipo chimathandizidwa ndi chimango chakunja kuti chitsimikizire kuti chisindikizo cha mafuta sichimawonongeka ndi kutentha kwambiri komanso kupanikizika kwakukulu; gawo la radial lili ndi kasupe wodzilimbitsa kapena waya wachitsulo, womwe nthawi zonse umatha kumamatira pamwamba pa tsinde la valavu, ndikupanga chisindikizo chosinthika. Ngakhale nthawi zambiri valavu ikatsegulidwa ndi kutsekedwa, imatha kuletsa kutulutsa kwa mafuta a injini patsinde.
Katundu Wazinthu: Thupi lalikulu la chisindikizo cha mafuta nthawi zambiri limapangidwa ndi fluororubber, yomwe ili ndi mphamvu zabwino kwambiri zotsutsana ndi kutentha kwambiri komanso kukana dzimbiri kwa mafuta, ndipo imatha kusunga kusinthasintha ndi magwiridwe antchito otseka injini ndi kutentha mpaka madigiri Celsius mazana angapo, kukana kuwonongeka kwa mankhwala a mafuta a injini.
Njira Yogwirira Ntchito: Pamene valavu yatsekedwa, chisindikizo cha mafuta a valavu chimakhala chotsekedwa, zomwe zimalepheretsa mafuta a injini m'chipinda cha valavu kuti asatsike kupita kuchipinda choyaka moto kapena kupita mmwamba m'mapaipi olowera ndi otulutsa mpweya; pamene valavu yatsegulidwa, chisindikizo cha mafuta chimayenda ndi valavu, koma chimadalira kapangidwe kodzilimbitsa kuti chikhalebe cholimba, kuonetsetsa kuti chisindikizocho sichikusokonezedwa.
Ngati chisindikizo cha mafuta a valavu chikakalamba kapena chawonongeka, mafuta a injini amalowa m'chipinda choyaka moto ndikuwotchedwa, zomwe zimayambitsa mavuto monga kuyaka mafuta a injini, utsi wabuluu wochokera mu chitoliro chotulutsa utsi, kuchuluka kwa mpweya woipa, komanso kuchepa kwa mphamvu. Chifukwa chake, kuyang'anitsitsa nthawi zonse ndikusintha ma vavu owonongeka ndikofunikira kwambiri kuti injini igwire ntchito bwino komanso ikhale ndi moyo wautali.
Kulephera kwa chisindikizo cha mafuta a valavu ya injini kumatanthauza kukalamba, kuwonongeka, kapena kulephera kwa chisindikizo cha mafuta a valavu, zomwe zimapangitsa kuti mafuta a injini alowe m'chipinda choyaka moto ndikuchita nawo ntchito yoyaka, zomwe zimayambitsa zochitika zingapo zachilendo. Ngakhale kuti chisindikizo cha mafuta a valavu ndi chaching'ono, ntchito yake ndi yofunika kwambiri. Chikawonongeka, chidzakhudza mwachindunji magwiridwe antchito a injini komanso moyo wake.
Zizindikiro zazikulu za kulephera kwa chisindikizo cha mafuta a valve
Utsi wabuluu wochokera ku utsi wa injini: Ichi ndi chizindikiro chodziwika bwino. Injini ikayamba, ikasiya kugwira ntchito, kapena kufulumira mwadzidzidzi, chitoliro chotulutsa utsi chimapitiriza kutulutsa utsi wabuluu, zomwe ndi chizindikiro cha mafuta a injini omwe amayaka mosakwanira.
Kugwiritsa ntchito mafuta mofulumira kwambiri: Popanda kutayikira koonekeratu, kuchuluka kwa mafuta kumatsika kwambiri mkati mwa nthawi yochepa (monga mkati mwa makilomita masauzande angapo), ndipo mafuta a injini amafunika kudzazidwanso pafupipafupi.
Kuchuluka kwa kaboni m'mapulagi a spark: Mafuta a injini akalowa m'chipinda choyaka moto, amapanga kaboni wakuda, wonenepa pamaelekitirodi a spark plug, zomwe zimapangitsa kuti kuyaka bwino komanso kuyambitsa kugwedezeka kwa injini, kusakhazikika, kapena kutayika kwa mphamvu.
Mphamvu ya injini yotsika, kuthamanga kofooka: Chifukwa cha kuchepa kwa magwiridwe antchito otseka silinda, kupanikizika kosakwanira, komanso kuchepa kwa mphamvu yoyaka, galimotoyo idzakhala ndi kuthamanga pang'onopang'ono komanso mphamvu yotulutsa yosakwanira.
Madontho a mafuta kapena chinyezi pamalo otulutsira utsi wa payipi: Zotsalira zofanana ndi mafuta kapena zizindikiro zonyowa zimatha kuwoneka pamalo otulutsira utsi wa payipi, limodzi ndi fungo loipa la mafuta a injini.
Utsi wabuluu wowonekera bwino kwambiri panthawi yozizira: Pambuyo poti chisindikizo cha mafuta a valavu chatha, mafuta a injini amalowa mu chitsogozo cha valavu galimoto ikayimitsidwa usiku, ndipo madzi amatuluka kwambiri injini ikakhala yozizira. Chochitika cha utsi wabuluu ndichodziwika kwambiri.
Zomwe zimayambitsa kulephera kwa chisindikizo cha mafuta a valavu
Kukalamba kwachilengedwe: Chisindikizo cha mafuta a valve nthawi zambiri chimapangidwa ndi rabara ya fluororubber kapena silicone. Chimayikidwa pa kutentha kwakukulu komanso kupanikizika kwa nthawi yayitali, ndipo rabarayo imauma, imasweka, ndikutaya kusinthasintha, zomwe zimapangitsa kuti kutseka kulephereke.
Kuwonongeka kwa mpweya: Kugwiritsa ntchito mafuta a injini osagwira ntchito bwino kwa nthawi yayitali kapena kuyendetsa galimoto mtunda waufupi pafupipafupi kungapangitse kuti mpweya ukhale m'malo osungira mpweya pa valavu, zomwe zimapangitsa kuti chisindikizo cha mafuta chikhale cholimba.
Kukhazikitsa kosayenera: Mukasintha, ngati palibe zida zapadera zomwe zagwiritsidwa ntchito, njira yoyikira si yolondola, kapena mafuta a injini sakuyikidwa, n'zosavuta kuwononga chisindikizo cha mafuta.
Kutenthedwa kwambiri ndi injini kapena mafuta osakwanira: Kutentha kwambiri kumathandizira kuti rabara ikule msanga, ndipo mafuta a injini osakwanira kapena malo otsekeka amafuta angayambitsenso kuti chisindikizo cha mafuta chilephereke.
Kodi mungatani ndi vuto la kulephera kwa chisindikizo cha mafuta a valve?
Chosindikizira cha mafuta cha valve sichingathe kukonzedwa ndipo chiyenera kusinthidwa.
Ndondomeko Yosinthira:
Ngati zotsekera za mafuta za valavu ya silinda imodzi kapena ziwiri zokha zawonongeka, chivundikiro cha valavu chingasiyidwe chopanda kuphwanyika, ndipo mpweya wothamanga kwambiri ukhoza kulowetsedwa kudzera mu dzenje la spark plug kuti ugwire valavu, kenako gwiritsani ntchito zida zapadera kuti mulowe m'malo mwake.
Ngati ma silinda atatu kapena kuposerapo ali ndi vuto, kapena injini yakhala ikuyendetsedwa kwa nthawi yayitali (monga makilomita opitilira 100,000), tikukulimbikitsani kusokoneza chivundikiro cha valavu yonse, kusintha zomatira zonse za valavu mofanana, ndikupewa kukonza pafupipafupi pakapita nthawi yochepa.
Zitetezo zosinthira:
Gwiritsani ntchito zida zoyambirira kapena zapamwamba (zopangidwa ndi silicone zomwe zimalimbikitsidwa, kukana kutentha bwino).
Njira yosinthira injini imafuna zida ndi ukadaulo waluso. Ndikofunikira kuti igwiritsidwe ntchito ndi malo okonzera zinthu nthawi zonse kuti zinyalala zisalowe mu injini kapena kuyika molakwika zomwe zingawononge injini.
Pambuyo posintha, tikukulimbikitsani kuyeretsa kaboni ya injini kuti mubwezeretse ukhondo wa chipinda choyaka moto ndi mphamvu zomwe zikugwira ntchito.
Malangizo opewera
Nthawi zonse sinthani mafuta a injini apamwamba kwambiri opangidwa ndi opanga ndipo sinthani fyuluta yamafuta malinga ndi momwe wopanga amalangizira.
Pewani kuyendetsa galimoto mtunda wautali komanso kungokhala chete pafupipafupi, zomwe zimathandiza kuti injini itenthe bwino, zomwe zimathandiza kuchepetsa mpweya woipa.
Samalani ndi kuyang'ana momwe galimotoyo ilili. Ngati mukuona kuti utsi wochuluka kapena mafuta akugwiritsidwa ntchito mofulumira, yang'anani mwachangu.
Nthawi yogwira ntchito ya valve oil seal nthawi zambiri imakhala pakati pa makilomita 80,000 ndi 150,000, koma imakhudzidwa kwambiri ndi malo omwe galimotoyo imayendera komanso momwe imachitira zinthu. Ngati galimotoyo ikuyandikira mtunda uwu, tikulimbikitsidwa kuti muyang'anenso nthawi zonse mukakonza.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
